Abstract
The invention discloses a cold rolling lubricating agent for a lead and lead alloy sheet strip. 32# oil for a total-loss system is used as base oil and is matched with various composite additives including an anti-wear agent, an oiliness agent, an antioxidant, a metal deactivator, an anti-forming agent, a non-emulsifying agent, a friction improver and the like. The cold rolling lubricating agent has the effects of lubricating, washing, cooling, reducing the roller and rolled piece bonding phenomenon and reducing the damage caused by sheet strip surface bonding.
Description
Technical field
The invention belongs to lead and alloy plate strip cold-rolling lubricant field thereof.
Background technology
Lead is bluish silvery white heavy metal, and it is toxic, is a kind of malleable main group metal.Fusing point 327.502 DEG C, boiling point 1740 DEG C, density 11.3437g/cm
3, hardness 1.5, quality is soft, and tensile strength is little.Lead is easy to get rusty---oxidation.Lead is often grizzly, be exactly due to it in atmosphere, very easily become the plumbous oxide of grey black by the dioxygen oxidation in air, make its argenteous gloss gradually become intensely dark.The important use of metallic lead manufactures store battery.The resistance to deformation of lead alloy is little, and ingot casting does not need the technique such as heating and available rolling, extruding to make sheet material, band, tubing, bar and wire rod, and does not need process annealing process.Because the shearing of lead alloy, creep strength are low, under certain load and rolling shear effect, lead alloy is easily deformable and thinningly become foil-like; And the self-lubricity of lead alloy, running-in ability and damping property are good, noise is little, because of but good bearing metal.Graphite metal and tinhase bearing metals are referred to as Babbitt metal, can make the Locomotive Bearing of high-load.Do not have the plumbous bright in color of zone of oxidation, density is high, and hardness is very low, and extensibility is very strong.Its conductivity is quite low, and corrosion resistance is very high, and therefore it is often used as the container of the strong material (such as sulfuric acid) of dress corrosion strength.Add the corrosion resistance that a small amount of antimony or other metal can improve it more.The tensile strength of lead alloy is 3 ~ 7kgf/mm
2, more much lower than most metals alloy.Antimony is for one of important element strengthening matrix, and only part is solid-solution in lead, both can be used for solution strengthening, and can be used for ageing strengthening again; If but too high levels, the toughness of lead alloy and solidity to corrosion can be made to degenerate.Consider from over-all properties, when lead alloy is for making the corrosion-resistant element such as chemical industry equipment, pipeline, to be advisable containing antimony about 6%; During for making transom, to contain antimony 8% ~ 10% as well.Lead antimony alloy adds a small amount of copper, arsenic, silver, calcium, tellurium etc., can gain in strength, be called antimonial lead.Lead alloy has not easily by the characteristic that X and gamma-rays penetrate, and can make the protective material of radiation work.
The resistance to deformation of usual pure lead increases with rolling reduction and increases, but Pb-Sb alloy under a certain pressure, and resistance to deformation has a maximum value.And this maximum value increases with antimony content and significantly increases.Plumbous have two distinguishing features in rolling: one is that chemical property is relatively active, so that in the operation of rolling, especially in hot rolling process process, easy and surrounding environment produces reacts and causes pollution, reduces processing characteristics; Two is rolls of very easily adhering.In view of lead has the character of tool and mould of very easily adhering, in the plumbous material operation of rolling, effective lubricant and lubricating method should be selected, carry out lubricating, clean, cool and reduce roll and rolled piece adherent phenomenon, reduce the damage that strip surface adhering causes.
Summary of the invention
The technical problem to be solved in the present invention is to provide one to be had and carries out lubricating, clean, cool and reduce roll and rolled piece adherent phenomenon, reduces lead and alloy plate strip cold-rolling lubricant thereof that strip surface adhering causes damage.
The present invention solves the problems of the technologies described above by following technical scheme: adopt oil based on No. 32 total loss system oil, coordinate multiple composite additive, its each component and mass percent thereof are:
| Component | Content (mass percent) |
| Base oil | 80%～85% |
| Anti-wear agent | 3.0%～4.0% |
| Oiliness improver | 5.0%～8.0% |
| Oxidation inhibitor | 0.3%～0.5% |
| Metal passivator | 3.0%～5.0% |
| Kilfoam | 0.001%～0.005% |
| Non-emulsifying agent | 0.2%～0.5% |
| Friction improver | 3.0%～5.0% |
Base oil is No. 32 total loss system oil.
Anti-wear agent is that dibutyl dithiocaarbamate is plumbous.
Oiliness improver is sulfurized lard.
Oxidation inhibitor is 2,2-ditertbutylparacresol.
Metal passivator is dialkyl diphenylamine.
Kilfoam is dimethyl silicone oil.
Non-emulsifying agent is polyethers macromolecular compound.
Friction improver is commercial fatty acids.
Lead of the present invention and alloy plate strip cold-rolling lubricant thereof have and carry out lubricating, clean, cool and reducing roll and rolled piece adherent phenomenon, reduce the function that strip surface adhering causes damage.
